Development Of Data Processing And Display&Control Software For Regional Security Radar

Data processing is the key technology of modern radar system.It is the process of forming the trajectory of the target and tracking target through the processing of point trace condensation,tracking filtering,multi-target association and so on,processing the original position,velocity,angle and other information of the target by radar signal processing.In recent years,with the continuous progress of radar technology,the amount of data provided by signal processing is increasing,the requirements for data processing are also increasing,and the application of security in civil area is increasing.Radar data processing and display & control terminal should not only realize real-time monitoring of the running state of radar host,but also process the data provided by radar host in real time,and present the detection results to users intuitively,which is convenient for operators to set parameters according to actual needs,realize friendly human-computer interaction,and complete the detection task efficiently.With the development of computer technology and network technology,software has become the development direction of radar terminal.The main research contents and results of this thesis are as follows:1.Point processing in radar data processing is studied,including coordinate conversion,outlier elimination,and traditional point trace data merging,distinguishing and condensing methods.The DBSCAN clustering method based on density is studied and applied to radar point trace processing.Through the simulation experiment,the above two different data processing methods are compared to verify the effectiveness of the points processing method based on density clustering.2.Track processing in radar data processing is studied,including track initiation,single target filtering,multi-target association,track maintenance and termination algorithms.Among them,the single target filtering algorithm includes Kalman filter,?-? filter and ?-?-? filter,and the multi-target association algorithm includes global nearest neighbor algorithm and joint probabilistic data association algorithm.The simulation simulates multiple motion scenarios of single target and multi-target,and verifies the above algorithms.3.Based on QT,a set of radar data processing and display & control terminal software is developed,including radar data processing,radar host status display and radar working parameters setting.The hardware design of the host supporting the terminal software and the functional requirements,development platform and development process of the software are introduced.The radar trace processing and track processing algorithms are realized and applied to the software.The test method of the software is discussed.The function of the terminal software is tested indoor.The radar data processing performance is evaluated through the field test,and the practicability and reliability of the terminal software are verified.
